Extraosseous myocardial uptake incidentally detected during bone scan: Report of three cases and a systematic literature review of extraosseous uptake

Abstract

Bone scintigraphy is widely considered as an important technique able to investigate various pathological conditions of the skeletal system. Many unexpected extraosseous uptakes have been reported in literature. We present here three cases of unexpected 99mTc-oxidronate (HDP) myocardial extraosseous purposes. In particular, we present the first reported case of a myocardial uptake in a patient with IgM-related amyloidosis. Subsequently, we perform a review of the existing literature about extraosseous uptakes. Copyright © 2013 Via Medica.
